IMPROVEMENT IN CISTERN-FlL-TERS, &c.

Specicationforming part of Letters Patent No. 177,049, dated May 2,1876;,app1icationvf11ed March 17, 1876.

To all whom it may concern: A

Be it known that I, WILLIAM B. WILSON, of Louisville, in the county ofJeferson, State of Kentucky, have invented certain new and usefulImprovements in Uistern-Filters and Water-Separators, of which thefollowing is a specification; and I do hereby declare that in the sameis conta-ined afull, clear, and exact ldescription of my said invention,refererence heilig had to the accompanying draw; ing, and to the lettersof reference marked thereon.

My invention relates to an apparatus adapted to receive water from theroofof'a building',

and conduct it, after a certain portion thereof has been utilized incleansing the said roof, to a cistern or other receptacle, in a pure andwholesome condition, and free from soot, coaldust, Ste., which usuallyaccompany rain-water to cisterns.

In the accompanying drawing, forming a part of this specification,Figure l is a vertical section of the invention, and Fig. 2 a side viewof the same. Y

A andB are pipes, connected at their upper ends, where they aresurrounded by a flange, a. 'Ihe said pipes diverge as they eX- tenddownwardly from the flange a, and form, together with the front and backplates b and c and the bottom plate d, the receiver G. D is a receptaclefor ballast, or a balance-chamber, situate on the outside ot' the pipeA, for purposes hereinafter described. E is a box inclosing the lowerends oftthe pipes VA and B, and is a fixture, the other parts of the aplparatus heilig susceptible ot' a vibratory movementupon a bolt, c,extending through the receiver O to a stationary object at the back ofthe same. F is a cup formed in the inner side of the pipe B', with whichit is in communication by means of a piece of gauze, f. A smallaperture, g, also connects the cup F with the pipe B, the oftice ofwhich will be hereinafter described. Parts of the apparatus not yetalluded to will be described, and their uses fully set forth in thedescription of the operation of the invention which follows. Thevibratory portion ot' the apparatus being in the position shown by thefull lines in the drawing, by reason of the balance-chamber seeking itslowest position, the pipe B is brought directly under the down-spout,which is represented by G. Ou a brisk shower or rain occurring, theWater from the roof containing impurities passes down the pipe B andover the gauze f to the ground, or to a waste pipe. A portion of thewater introduced into the pipe B,however,passes through the gauge fintothe cup F, and thence by means of an aperture, It, to the receiver. Thereceiver is by this means increased in weight, and gradually overcomesthe tendency to remain in the-position whichit occupies and graduallyfalls, carrying the upper en of the pipe A directly underneath thedownspout G. By this` time the root is supposed to be cleansed, and thewater from the down'- spout is transferred by means of the pipe A to thecstern. This positionot' the moving parts of the apparatus is maintainedunt-il the rain ceases, an opening, t', in the side of the pipe Aadmitting water to the receiver to keep up the requisite quantitytherein, and to overcome the leakage from an aperture in thebottomtthereof, which serves to relieve the receiver after the rain hasstopped. After the emptying of the receiver, a reverse movement of theparts takes place, and they vassume their original positions. The smallaperture g, connecting lthe lower part of the cup F with the pipe B, isdesigned to relieve the cup of dew or water from showers too light toproduce the results described.

Having thus described my invention, what I claim as new, and wish tosecure by Letters Patent of the United States, is

rIhe pipes A and B, connected at their upper ends and divergin gdownwardly and separated by the receiver C, cup F, provided withapertures h and g, gauze f, and balanceehamber I), all hanging upon 0rpivoted to the bolt e, in combination with the stationary down-spout G,substantially as and for the purpose set forth.

In`testilnony whereof I have hereunto subscribed my name.

WILLIAM B. WILSON'.
